This does not actually answer the question, or rather it maybe confirms it.
This is a lawless gospel because the law and its power is nailed to the cross.
Paul says this
having canceled the charge of our legal indebtedness, which stood against us and condemned us; he has taken it away, nailing it to the cross.
col 2:14
So what was nailed to the cross was ones past legal indebtedness which has now
been taken away. The law still condemns if sin is commited, it is just past missdeeds
are forgiven and cleansed.
This is a long way from saying sin is ok and a further debt is not created by sinful
behaviour. It is clear from scripture David was cleansed of sin, yet he still sinned
with Bathsheba, but when challenged confessed and repented.
Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. 6 Because of these, the wrath of God is coming. 7 You used to walk in these ways, in the life you once lived. 8 But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips. 9 Do not lie to each other, since you have taken off your old self with its practices 10 and have put on the new self, which is being renewed in knowledge in the image of its Creator.
Col 3:5-10
This is very much obedience to the law of Christ, specifying what is acceptable
behaviour and what is not. This is very odd is all law or measures or goals are
now removed.
